Williams, Dayton, Ohio, assigner to Chrysler Corporation, Detroit, Mich., a corporation of Delaware Application May 6, 1940, Serial No. 333,515 n 4 claim. The present invention covers an improvement l in the art of air conditioning and has particular reference to means for mounting a window ledge air conditioning unit on the'ledge of a window or other opening in order that the unit may be conveniently swung to one side when the window is opened for the purpose of permitting ingress and egress therethrough, especially in order that the outer surfaces oi' the window panes may be washed. The invention has particular utility with respect to the installation of air conditioning units of this character in tall buildings where a window unit, balanced on the window ledge when the window is open, constitutes a serious danger to life, not only of window washers attempting to straddle the unit or to climb over the unit to the window ledge, but to passersby who might be struck down by an accidentally dislodged unit.

The principal object of the present invention is to provide means whereby a window ledge air conditioning unit of the character disclosed in the copending applications of Bernard W. Jewell, Serial No. 244,629, filed December 8, 1938, now Patent No. 2,198,500, Serial No. 303,968, flied November 13, 1939, and Serial No. 303,969, led November 13, 1939, or my copending application,

Serial No. 303,965, led November 13, 1939, may` be safely and firmly retained in position on a window ledge or other opening in the wall of an v enclosure.

Another object of the present invention is to provide means whereby a unit of the window ledge type may be anchored in place in the position of use by means preventing the tipping of the unit from its position, which anchoring means constitutes means to permit swinging movement of the Window ledge unit from its position of use to a position inside of the room in order that unhampered egress through the window may be permitted.

Another object of the present invention is to provide means having the foregoing advantages and characteristics and including a lifting device for raising the unit clear of the supporting window ledge in order that the unit may be swung inwardly into the room.

These and other objects and advantages of the present invention may vbe readily ascertained from the following'speclcation and the accompanying drawings wherein like numerals refer to like parts throughout.

' Fig. 7 is a view similar to Figs. 1 and 5, and showing another modiiication of the present invention; and

Fig. 8 is a view similar to Figs. 2 and 6, showing a side elevation of the construction shown in Fig. 7. e

Figs. l to 4, inclusive, disclose a wall I0 having a window therein framed by the usual side'frames II and I2, lintel I3, and ledge Il. The window opening is provided with an upper window I5 and a movable lower window Iii framed by sash members including the lower sash I'I of window IB. A window ledge air conditioning unit is shown in position upon the ledge I4, the openings beneath the bottom sash Il at the sides of the unit being blocked by side wings 2| and 22. The enclosure may be completed by lowering window I'B until sash I'I rests upon the tops of the unit 20 and the side wings 2| and 22, the movable window being preferably locked in position so as to assist in retaining the unit on the window ledge.

In order that positive retention of the unit and swinging movement thereof from the position of use may be accomplished, there is provided anchoring means comprising a post pivotally attached to a member 26 fastened to or imbedded in the window ledge. The member 26 supports a box cam 21 on its upper surface which is iixed to post 25 and upon which rests the pivot portion of a supporting bar 28 pivotally retained on the post 25. The pivot. portion of the bar 2l is free to rise vertically as forced by the cam 21 but is preferably retained from accidental dislodgment from the post by a cap 30 on the 2 top of the short post. The lbar 28 extends beneath the bottom of the portion of the unit extending into the room as close to the window ledge as possible in order as close to the center of gravityof the unit as possible. The member 26 may be a attached to the post as by riveting over a reduced portion of the post at 3l in order that the post may turn with respect to the member 26. A clevis 36 ispreferably passed about the unit with its ends bolted to the bar 23 in order firmly to fasten the unittothe bar.

that the bar shall be When the unit is in the position of use the v side wing 2|, which 'abuts the right side of the unit and the right side of the window opening, blocks the opening left between the unit and the window edges. This side wing may be xed in position by'screws fastened to the window ledge and sash guide as shown in Fig. 3. In order that the unit may be quickly moved to one side, a removable side wing 22 is preferably provided at the left side of the unit which may comprise a panel member 36 having its outer extremity slidably guided in the sash guides, anda. panel member 31 having its inner edge slidably guided-in a guide member 38 fastened to the left side of the unit. The members 36 and 31 may be retained in adjusted position as shown by bolts 39 fastened t'o member 36 and passing through slots 40 in member 31 and retained by wing nuts 4I. Swinging of the unit is permissible after raising the movable window I6, sliding the sidewing member 36 inward after loosening nuts 4I and removing the side wing .22.-

In order that absolute stability of the unit may be provided during the swinging movement thereof and while it is in the position inside of the room as shown in skeleton outline in Fig. 3, means for supporting the weight of the unit are preferably provided, which means may comprise straps fastened to a hook or pivot member `46 on the Alintel I3 at'the right side of the window and preferably substantially vertically above the post 25. The straps hang at theside of the window when the unit is in the position of use so as to be out of the way and unnoticeable. The lower extremityof each strap is provided With a hook 41 which is adapted to engage an eye 48 on the upper left edge of the unit, preferably retained thereon by bands 49 passing about the unit. The length of each strap is preferably such as to require lifting of the unit a short distance in order to engage the hooks 41 in the eyes 48 so that the bottom of the unit will clear the Window ledge when the hooks are so engaged. This llftingof the unit is possiblebecause of the loose, pivotal engagement of the bar 28 with the post 25 .and may be accomplished by lifting the left side of the unit While turning the cam 21 as by means of the capstan lever 50 provided on the cap 30. When the unit has been so raised and the side wing 22 removed, the unit may .be swung to the inner position where it will be supported until returned to the position of use.

A more rigid construction may by means ofextending the pivot post upward as shown at 25" in Figs. 5 and 6, the vertical post being retained in position as by means of bolts fastened into the wall construction.

Another modification is disclosed in Figs. 7 and 8, wherein vertical support is achieved by fastening a bar 2,8 and gusset member 6I firmly to an extended pivot post 62 rotatively retained in brackets 63 and 64 fastened to the wall construction beneath the window ledge I4 and supported be provided as in a socket member 65 fastened to the door. A clevls 35 may be fastened about the unit and bolted to the end of bar 28' and to the top of post 62 in order to firmly join the unit to the supporting structure. In this instance raising of the unit from the window ledge may be entirely accomplished by a cam member 66 inserted in the socket member 65 beneath the bottom of post 62 and which may be rotated by a bar 61 passing through a slot 68 in the side of the socket member. If desired, of course, a strap 45 and eye 46 may be provided.

In some instances the unit may be provided with adjustable supporting legs 10 extending from the unit to the outer surface of the window ledge in which case such legs should be so fastened to the unit as to be pivotally or otherwise movable to a position above the lowermost extremity of the unit. The unit may be provided with an air and noise deflecting hood 55 at its outer end which is accordingly preferably pivoted to the outer top edge of the unit by hinge members 56 in order that the hood may be swung back upon the top ofthe unit to lessen the length of the construction so that the unit may be swung through narrow windows. It may be seen, however, in Fig. 3 that the unit maybe mounted in a window much narrower than the drawings suggest.
